IMPLANT FOR FUSION OF BONES AND/OR BONE PARTS - In an implant for fusion of bones or bone parts, particularly of the carpal region of a wrist, as well as for application of compression between the bones or bone parts, a base body with bone screws is provided, which are guided in recesses that possess a geometry by means of which the compression between the bone, in each instance, can be adjusted, whereby the base body is configured with rotation symmetry. The geometry of its recesses has the shape of an oblong hole curved in the circumference direction of the base body, in each instance, whose curvature, with reference to the central axis of the base body, runs at an incline to this axis, in such a manner that the bone screws screwed into the bones and guided in the recesses in the manner of a motion link can be moved in the direction of the inclined oblong holes, radially toward the central axis of the base body, by means of a rotational movement of the base body.
